2. People

2.1. Patient

2.1.1. located in the middle on the bed

2.1.2. Middle aged woman with metastatic appendiceal cancer

2.1.3. already underwent cytoreduction

2.2. Surgeon

2.2.1. located to the right side of the patient abdomen

2.2.2. mainly performs the HIPEC surgery

2.3. Assistant 1

2.3.1. located to the left side of the patient abdomen
